The Family Connection
If a parent has ADHD, a child has more than a 50% chance of having it. If an older sibling has it, a child has more than a 30% chance.
Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Simply put, people with ADHD have areas of the brain that function differently. The disorder begins in childhood, but somewhere between 30 to 70 percent of sons will also be fathers with ADHD. A number of published studies show a clear link to genetics, but it is not 100 percent conclusive.
Studies show that if you have ADHD, your children have about a 35% chance of acquiring it; if a child has it, there is a 50% likelihood that one of his or her parents does as well.
It's a common misconception that ADHD is something that you can grow out of, develop at any stage in your life and is curable. The fact is, ADHD is a neurodevelopmental disorder, which means that the brain hasn't developed neurotypically from birth.
ADHD more common in offspring of mothers with genetic serotonin deficiencies. Summary: Children whose mothers are genetically predisposed to have impaired production of serotonin appear more likely to develop attention-deficit hyperactivity disorder later in life, according to a new report.
A rare, autosomal recessive inherited disorder usually caused by mutations in the THRB gene.
Attention deficit hyperactivity disorder (ADHD), one of the most prevalent childhood disorders today, is generally more likely to be diagnosed and treated in boys than in girls.
The risk of attention deficit hyperactivity disorder (ADHD) increases for firstborn children compared with the youngest born and single children, according to a German study published in the Journal of Attention Disorders.
Many women with ADHD say they feel restless all the time. They might have a hard time relaxing or tap their fingers and toes incessantly. Adults with impulsivity problems might spend irresponsibly and are more likely to get into car accidents. They also have higher rates of divorce and addiction.
ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.
Greatest heredity from mother
Absolutely most at risk were sons with parents who were both diagnosed with ADHD: - 40 percent of these boys are themselves diagnosed with the condition, says Solberg.
Boys (13%) are more likely to be diagnosed with ADHD than girls (6%). Black, non-Hispanic children and White, non-Hispanic children are more often diagnosed with ADHD (12% and 10%, respectively), than Hispanic children (8%) or Asian, non-Hispanic children (3%).
Girls are also less likely to be diagnosed earlier because they often display more symptoms of anxiety. Medical providers may only treat a female patient's anxiety or depression without evaluating for ADHD. Hormones, which affect the symptoms of both ADHD and anxiety, can complicate things.
Children were assessed with neuropsychological paradigms measuring IQ, motor, timing, and executive functions. Results: Paternal and maternal ADHD were equally positively related to ADHD in offspring.
Dopamine D5 receptor gene (DRD5)
Another dopamine receptor gene, DRD5, on chromosome 4p15. 1-15.3 also appears to be important.
About 40% of ADHD children have at least one parent with clinical ADHD symptoms.
The exposure to stressful life events, and—more specifically—Childhood Trauma, has been shown to predict ADHD onset as well as persistence of the disorder into adulthood (Biederman et al. 1995; Friedrichs et al.
Barkley, PhD. “Children diagnosed with ADHD are not likely to grow out of it. And while some children may recover fully from their disorder by age 21 or 27, the full disorder or at least significant symptoms and impairment persist in 50-86 percent of cases diagnosed in childhood.
ADHD symptoms start before age 12, and in some children, they're noticeable as early as 3 years of age. ADHD symptoms can be mild, moderate or severe, and they may continue into adulthood. ADHD occurs more often in males than in females, and behaviors can be different in boys and girls.
ADHD in children may present through symptoms including inattentiveness, impulsivity, hyperactivity, fidgeting, excessive talking, trouble waiting turn, and difficulty following direction.
Overall population incidence is felt to be 8%-10%. Several investigations have demonstrated that children who have ADHD usually have a least one close relative (child or adult) who also has ADHD. At least one-third of all fathers who have ADHD will produce a child with ADHD.
Genetic screening cannot determine if a person has ADHD. Genetic screening may be helpful to a prescriber in selecting medications to treat ADHD and related conditions. Genetic screening may reveal information about other conditions that will need to be considered.
